What is the value of x if 25 = 5x + 35 ?

For this case we have that by definition, the surface area of a cone is given by:

Answer:

california by 205.2

Step-by-step explanation:

3.8 times 107=406.6-California

1.9 times 106=201.4-Nebraska

205.2

Answer: The Population of California is larger than the population of Nebraska by 20 times

Step-by-step explanation:

Given

Population of California , [tex]P_C=3.8\times 10^{7}[/tex]

and population of Nebraska, [tex]P_N=1.9\times 10^{6}[/tex]

From above data it is clear that the population of California is larger than the population of Nebraska

And Ratio, [tex]\frac{P_C}{P_N}=\frac{3.8\times 10^{7}}{1.9\times 10^{6}}=\frac{38}{1.9}=20[/tex]

Thus the population of California is larger than the population of Nebraska by 20 times

If we change those mixed fractions to improper we will have a much easier time with them:

Answer:

7

Step-by-step explanation:

3x - 6 = 15

+6 +6

____________

3x = 21

3x = 21/3

x = 7

The value of x that satisfies the equation 3x - 6 = 15 is x = 7. This was calculated by isolating x and solving the equation.

The equation provided is 3x - 6 = 15, and the value for x that satisfies this equation is what we are looking for. To solve for x, we can start by adding 6 to both sides of the equation to isolate 3x on one side which results in 3x = 21. Finally, we divide each side by 3 to find the solution which gives us x = 7. Therefore, the solution to the equation 3x - 6 = 15 is x = 7

Answer:

x = 5/16

Step-by-step explanation:

"Solving this equation" means determining the x value that makes the equation true.  Since it's a linear equation, there can be only one solution.

Starting with 32x – 1 = 16x + 4, subtract 16x from both sides, obtaining:

16x - 1 = 4

and then add 1 to both sides, obtaining 16x = 5.  Then x = 5/16.

Answer:

c. (3.75, 3.5)

Step-by-step explanation:

Let's call the given segment AB, and the dividing point P. Then you want AP:PB = 1:3.

There are a couple of ways you can get there.

1. Recognize that when you subtract the coordinates of A from P, the difference will be 1/4 of the result of subtracting A from B. That is, ...

P-A = (1/(1+3))·(B-A)

We can see that B-A = (6,8) -(3,2) = (3, 6), so 1/4 of that is (3/4, 3/2) = (0.75, 1.5). Adding these values to the coordinates of A gives ...

P = A + (.75, 1.5) = (3.75, 3.5)

__

2. Finish working out the equation above to solve for P:

4(P -A) = B -A

4P = B + 3A

P = (3A + B)/4 . . . . . note the multiplier for A is the relative length of PB and vice versa

P = (3(3, 2) +(6, 8))/4 = (15/4, 14/4) = (3.75, 3.5)

[tex]f(x) =x^3-6x^2-13x+42[/tex]

EXPLANATION

The zeros of the cubic function is given as:

x=7,x=-3,x=2

This implies that, x-7,x+3,x-2 are factors of the given cubic polynomial function.

We can write the completely factored form as a function of x to get:

[tex]f(x) = (x - 7)(x + 3)(x - 2)[/tex]

We expand to get:

[tex]f(x) = (x - 7)(x^2+ x-6)[/tex]

[tex]f(x) =x^3-6x^2-13x+42[/tex]

This is a cubic function because the highest degree is 3.

Answer:

(x, y) → (−x, y)(x, y)

Step-by-step explanation:

To do a transformation over the Y-axis, you just have to change the sign on the x in order to create a matching point on the other side of the Y axis, for example if you wish to make a reflection of the point (8,9), the reflection over the Y axis would be (-8,9), the same with X and Y, if you wish to make a reflection of (x,y) you just change the sign of the x like this: (-x,y)

The correct answer is option 1. [tex](x,y) \rightarrow (-x,y)[/tex]

To determine which transformation represents a reflection over the y-axis, we examine the options provided:

A reflection over the y-axis transforms the x-coordinate of a point to its opposite while keeping the y-coordinate unchanged. Therefore, the correct transformation is [tex](x,y) \rightarrow (-x,y)[/tex].

Reflection over the y-axis results in the point (x, y) being mapped to (−x, y). This is because the x-coordinate is negated while the y-coordinate remains the same.

The complete question is:

Which transformation represents a reflection over the y-axis?

1. [tex](x,y) \rightarrow (-x,y)[/tex]

2. [tex](x,y) \rightarrow (x,-y)[/tex]

3. [tex](x,y) \rightarrow (y,x)[/tex]

4. [tex](x,y) \rightarrow (-y,x)[/tex]

You must do pythagorean theorem:

a^2 + b^2 = c^2

a and b are the legs and c is the hypotenuse

In this triangle...

a = 16

b = x

c = 34

so...

16^2 + x^2 = 34^2

256 + x ^2 = 1156

x^2 = 900

Then to isolate x square root both sides. This will get rid of the square on the x value.

This will give you...

Answer: second option

Step-by-step explanation:

You need to apply the Pythagorean theorem:

[tex]a^2=b^2+c^2[/tex]

Where "a"  is the hypotenuse and "b" and "c" are the legs of the right triangle.

In the figure you can observe the value the hypotenuse of the right triangle and the value of one of this leg. Then, you need to solve for the other leg from [tex]a^2=b^2+c^2[/tex]:

[tex]b^2=a^2-c^2[/tex]

[tex]b=\sqrt{a^2-c^2}[/tex]

Substituting values, you get that the value of "x" is:

Answer: He has 45.61

45.61

Total money John has now is 45.61.

On the first day of the month, John had $28.35 and received an additional $17.26.

To find out how much money John has now, you need to add the initial amount to the additional money he received. Therefore, John now has

28.35 + 17.26 = 45.61 money

The two smallest positive solutions, with a < b, are approximately

x ≈ 0.384 and x ≈ 1.64.

We have,

Isolate the sine function by dividing both sides by 8.

sin(5x) = 3/8

The inverse sine function (also called arcsin) is on both sides of the equation.

5x = arcsin(3/8).

Divide both sides by 5.

x = (1/5) arcsin(3/8)

Now,

arcsin(3/8) is approximately 0.4115.

So,

x = (1/5) * 0.4115

x = 0.384.

Since the sine function repeats itself every 2π radians, we add multiples of 2π/5 to the solution to find other valid values of x.

The second smallest positive solution

x = 0.384 + (2π/5) = 1.64.

Therefore,

The two smallest positive solutions, with a < b, are approximately

x ≈ 0.384 and x ≈ 1.64.

The equation 8 sin(5x) = 3 is solved by isolating the variable term, using inverse sine to get an angle, and considering the period of the sine function when finding additional solutions.

To solve the equation 8 sin (5x) = 3, we first isolate the term involving the variable 'x'. Start by dividing both sides by 8. We get sin(5x) = 3/8.

The inverse sine (also known as arcsin or sin^-1) is used to get the angle whose sine is 3/8. So we have 5x = sin^-1(3/8).

To solve for 'x', we then divide both sides by 5: x = sin^-1(3/8) / 5.

This value of 'x' is a solution, but sine function repeats every 2π intervals, so we add multiples of 2π/5 to 'x' to get additional solutions.

The percentage of the company she owns is equivalent to 5%.

In mathematics →

Given is that if Ruth contributed $10,000 toward the total group investment of $200,000 for the purchase of a seafood restaurant.

Assume that the percentage of the company she owns is equivalent to [x] percent. So, we can write -

10000 = [x]% 0f 200000

10000 = [x]/100 × 200000

10000 = [x] × 2000

Step-by-step explanation:

Similar triangles have their corresponding sides to be in equivalent ratios

The length of PR is 31.5 inches

△WKT∼△NRP  means that, the following sides are similar

So, we have the following equivalent ratio

[tex]WK : TK = NR : PR[/tex]

From the complete question, we have the following parameters:

So, the ratio becomes

[tex]14 : 18 = 24.5 : PR[/tex]

Express the ratio as fraction

[tex]\frac{18}{14}= \frac{PR}{24.5 }[/tex]

Multiply both sides by 24.5

[tex]\frac{18}{14} \times 24.5= PR[/tex]

This gives

The volume of the cone is one-third of the product of its base area and its height. It is given by the formula,

The Volume of Cone = (1/3) × π × (d/2)² × h

The volume of wax that is needed to make a single candle with a diameter of 3 cm and height of 5 cm is,

Step-by-step explanation:

The distance of interest is apparently not the straight-line distance from the top of the vertical ladder to the ground (20 ft), but the length of the arc the top of the ladder makes as it rotates. That arc length (s) is given by ...

Here, the radius is 20 ft, and the angle is the supplement of 85°, or 95° = (95/180)π radians.

  s ≈ (20 ft)·(1.65806 radians) ≈ 33.16 ft ≈ 33 ft
